Well, I write this from a month long stay. If you are in town for a week, this is a fantastic place to stay, its close to Lumphini for nice morning walk with dragons and cats, its very close to Silom and a nice walk through the park. The staff is wonderful, I really liked them alot, they cross cover the front reception, in room dining etc. and really are so warm and welcoming. There are so many restaurants in this neighborhood its insane, my favorite was Artur (on Tomson) and Per Te. Le Beouf was also quite nice.
However in my excitement to find a place that I could actually see the address on Langsuan (as hidden per Airbnb guidelines) so I booked it immediately. I then went back to try to cancel the booking once I realized it was a studio and would not server my needs but could not get my money back because of LuXX cancellation rules. When I am here in Bangkok, I stay at least 40 to 60 days and need to be in someone's house - with a washing machine and full kitchen. My original room was on 422 and the wireless was good. I then moved to a suite with kitchen no washer (quite pricey in comparison with other units on Langsuan) once I moved into the Suite, the wireless was basically non existent. That was room 317. The problem with that is much of my work is from my unit so I had to borrow offices at Chula and also Bumrungrad to get work done.
What was not my fault was the constant construction and dogs barking (screaming howling actually ) every day around 4 to 4:20 pm. I don't know what that was about but I was actually out in the neighborhood investigating but could never quite figure out where on Langsuan they were at. Anyhow for a short stay in Bangkok, you can't beat it.
